RaspberryPi NSM

Suitable for a home 'blackbox' deployment - it will record everything that happens on your network. Use it to detect threats and/or to provide network forensics to a malware lab. Primarily I've used this over the last few months to learn more about Bro.

If your looking for something more suitable for the enterprise look at Security Onion.

for home/lab use the IDS performs adequately well - its dropped 10,000 packets after receiving nearly 1,000,000! My broadband speed is 40 Mbps which is perfectly fine for the IDS to cope with. If you need extra performance, avoid running it on a Raspberry Pi and look into caching mechanisms such as NTOP's PFRING/ZC modules which come shipped with Security Onion.

I've not created any dashboarding but you could spin up a VPS ELK instance and ship the logs securely to the cloud if you didn't fancy building one from scratch. Otherwise I'd recommend you build one locally using ELK/Splunk/Graylog.
